Chalcedony is known as the sister jade of agate, and I believe few people know this. Then we should pay attention to the difference between agate and chalcedony when choosing, and choose the one you want to buy.
There are three main differences between agate and chalcedony:
1, texture
This is the most basic difference between chalcedony and agate, and it is the easiest to judge the difference between the two. In ancient times, a method for judging agate and chalcedony was made to see whether there was a strip-like pattern on the outside. It can be basically concluded that there is basically no chalcedony without this trait, and there is a distinct strip. The texture can be called agate;
2, internal structure
Although chalcedony and agate are both of the same type of quartz, the main internal component is silica, but the internal structure is also different because of the different formation conditions. Chalcedony is a hard crystalline quartz (mainly containing water), so it is closer to crystal; but agate is not, mainly a gel of dehydrated silica, resulting in a less transparent and chalcedony;
3, construction
Chalcedony belongs to the cryptocrystalline aggregate and is densely packed. It can also be a spherulitic, radial or fine fibrous aggregate. Trigonal crystal system. Often formed into a dense block shape to form various structures, such as breast, grape, tuberculosis, etc., common concentric structure, color, depending on the type and amount of impurities contained in it, usually in the form of strips, Concentric ring, cloud or dendritic distribution;
Although the composition of the chalcedony and agate are roughly the same, the effects of each are quite different. In a sense, the effect of agate is stronger than that of chalcedony (agate is one of the seven treasures of Buddhism. The effect), at this point is unmatched by chalcedony.
